Embodiment 1
[0032] This embodiment provides a surgical navigation system based on lesion image projection. The surgical navigation system includes: an image processing module, an image fusion module, a three-dimensional reconstruction module and a surface acquisition module.
[0033]Specifically, the above four modules perform data interaction through the software core control system, and call various databases (such as image fusion algorithm database, image calibration algorithm database, machine vision algorithm database, etc.) through the software core control system, such as figure 2 Shown is a schematic diagram of a surgical navigation system.
[0034] The image fusion module is configured to fuse the pre-acquired first CT lesion image and the first MRI lesion image according to the image fusion algorithm database to obtain the first lesion image.
[0035] Specifically, the function of the image fusion module here is to display the different contents of different medical images (CT...
Embodiment 2
[0051] This embodiment provides another surgical navigation system based on lesion image projection. The surgical navigation system includes: a core layer, a functional layer, and an application layer; the core layer includes a software core control system, an image fusion algorithm database, an image calibration algorithm database, and a machine vision algorithm database; the functional layer includes an image processing module and an image fusion module. , 3D reconstruction module, surface acquisition module, codec module and data security module; the application layer includes: function interaction module, independent image display module, help and reminder module and system setting module, such as image 3 shown.
[0052] Specifically, the main function of the core layer is to provide precise control and real-time computing work for the functional layer. The core control system of the software at the core layer is the center of the software, providing communication betwee...
Embodiment 3
[0086] An embodiment of the present invention provides a surgical navigation method based on lesion image projection, such as Figure 4 As shown, the surgical navigation method includes:
[0087] Step S402, according to the image fusion algorithm database, the pre-acquired first CT lesion image and the first MRI lesion image are fused to obtain the first lesion image.
[0088] Step S404, adjusting the image quality of the first lesion image to obtain a second lesion image; wherein, the second lesion image is a two-dimensional image.
[0089] Step S406, performing three-dimensional splicing and combination on multiple second lesion images to obtain a third lesion image; wherein, the third lesion image is a three-dimensional image.
[0090] Step S408, collecting the real image of the patient's current diseased part, and correcting the real image according to the machine vision algorithm database to obtain the corrected real image.
[0091] In step S410, the third lesion image ...
